The comment states that the field is only used for rt61pci and rt73usb.
However, it is now used by rt2800pci and rt2800usb as well, so the
comment is not correct anymore.
Update the comment to not state any low-level drivers anymore.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

Tx bundling is the more efficient use of SDIO bus and allows more packet
transfers with fewer bus transactions, and is a way to improve overall
throughput. However, Tx bundling has only 4 scatter request resources available.
When there are multiple traffic streams of different priorities, it's possible
that lower priority traffic may hog all the scatter requests and lock out the
higher prioirty traffic from bundling.
Tx bundling is now enabled per AC. When an AC do a scatter request and
the remaining scatter request resources is lower than a configurable
threshold, it will disable Tx bundling for all AC's of lower priorities.
When an AC has Tx bundling disabled and has no Tx bundles sent in a
consecutive and configurable number of packets, Tx bundling will be re-enabled
for that AC.

When debugging firmware issues it's not always enough to get
the latest firmware logs, sometimes we need to get logs from a longer
period. To make this possible, add a debugfs file named fwlog_block. When
reading from this file ath6kl will send firmware logs whenever available
and otherwise it will block and wait for new logs.

Currently firmware logs are stored in a circular buffer, but this was
not very flexible and fragile. It's a lot easier to store logs to struct
skbuffs and store them in a skb queue. Also this makes it possible
to easily increase the buffer size, even dynamically if we so want (but
that's not yet supported).
From user space point of view nothing should change.

Some devices (iwl5100) cannot connect to zd1211rw based AP. It appears that
zd1211 firmware messes up duration_id field if it is not set to zero by driver.
Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits
14 and 15 set and other bits appearing random. Setting duration_id at driver to
zero results zd1211 outputting sane duration_id. This means that firmware is
setting correct values itself and expects duration_id to be zero in first
place.
Looking at vendor driver shows that only PSPoll frames have duration_id set by
driver, for other frames duration_id left zero.

Subject: [PATCH] net: enable TC35815 for MIPS again
TX493[8,9] MIPS SoCs support 2 Ethernet channels of type TC35815
which are connected to the internal PCI controller.
And JMR3927 MIPS board has a TC35815 chip on board.
These dependencies were lost on movement to drivers/net/ethernet/toshiba.

No need to maintain a parallel net_device_stats structure in
sh_eth_private, since we have a generic one in netdev
Fix two dma_map_single() incorrect parameters, passing skb->tail instead
of skb->data. Seems that there is no corresponding dmap_unmap_single()
calls for the moment in this driver.

When this GETHER controller received a large frame (about 1800 bytes
or more), skb_over_panic() happened. This is because the previous
driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size
is smaller than 4096 bytes. So, the controller accepted such a frame.
The controller can discard a large frame by the RFLR setting.
So, the patch modifies the value of RFLR to mtu + ETH_HLEN +
VLAN_HLEN + ETH_FCS_LEN.

commit 21a4e469 (netdev: ethernet dev_alloc_skb to netdev_alloc_skb)
should have used "ndev" instead of "dev".
This causes the following build errors:

We allocate memory for 'new_data' with kmalloc(). If we get the memory
we then try to build_skb() and if that should fail (which it can) we
do not enter 'if (likely(skb)) {' and actually use 'new_data' but
instead fall through to the 'drop:' label and end up returning from
the function without ever assigning 'new'data' to anything or freeing
it. That leaks the memory allocated to 'new_data'.
This patch fixes the memory leak by doing a kfree(new_data) in the
case where build_skb() fails (or where allocation of 'new_data' itself
fails, but in taht case it's just a harmless kfree(NULL)).

As it is, with PCI/ISA/MCA/CCW all set to n and PCMCIA set to m
setting TR to y will set LLC to m, with very unpleasant results -
net/802/psnap gets picked into obj-y, resulting in the kernel
that won't link - psnap calls functions from llc. The cause,
AFAICS, is that kconfig gets rev_dep for LLC containing
|| TR && (deps for TR)
and even though TR is boolean, both LLC and PCMCIA are tristate
and that thing becomes || y && (n || m), i.e. || m. The reason
for dependency on PCMCIA is that when none of PCI, ISA, MCA, CCW
or PCMCIA is set there'll be no tokenring drivers, so there's no
point building tokenring core. Proper fix probably belongs in
kconfig (we need strict and, such that y <strict_and> m would be
y, so that rev_deps added for tristate selected by bool would
use that instead of &&; we'd have || TR <strict_and> (deps for TR)
in this case), but it's a rather intrusive change. There's an
easy workaround in case of TR -> LLC select, namely to have a def_bool y
symbol sitting under if TR and have that symbol selecting LLC.
Kudos to johill for suggesting that one...

The majority of the e1000e code checks most function return values using a

of 'if (ret_val == 0)'. This patch converts the latter to the former for

The existing ITR code is broken and confusing, with lots of similarly-named
variables that do different things. Additionally, after the driver carefully
determines the optimal interrupt rate for the adapter, it then
ignores it and always writes a fixed, suboptimal value.
This patch refactors that code to make variable names more descriptive of
what they actually do, and then actually writes the calculated result to
the hardware.
Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps
to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.
